This book is aimed at newcomers to the field of logical reasoning, particularly those who, to borrow a phrase from Pascal, are so made that they understand best through visuals. I have selected a small set of common errors in reasoning and visualized them using memorable illustrations that are supplemented with lots of examples. The hope is that the reader will learn from these pages some of the most common pitfalls in arguments and be able to identify and avoid them in practice.
The literature on logic and logical fallacies is wide and exhaustive. This work’s novelty is in its use of illustrations to describe a small set of common errors in reasoning that plague a lot of our present discourse.
